>Capitalism has already been around forever :)

Much of Europe, for example, was feudalist until around the mid 17th century. To put it simply, the king owned all the land, and those who lived on it were divided into those who worked, those who fought, and those who prayed. Under no reasonable definitions could this be considered capitalism - even Marx viewed feudalism as the order coming before capitalism.

And most people likely thought that there couldn't be other forms of society. Divine rights of kings.
